World's Finest Comics #132

In a twist of time and tedium, Batman and Robin find themselves whisked into the medieval era by the rogue antics of Professor Carter Nichols and his time machine, leaving their modern-day foes in the dust. With the duo trapped in a world of castles and chaos, Superman must leap through history to restore the balance—before the past becomes their permanent prison.

In "The Fish in the Iron Mask," Aquaman and Aqualad are thrown into confusion when Topo the octopus—normally a trusted ally—suddenly dons an iron mask and launches attacks against the Sea King. As the aquatic duo investigates, strange forces begin to surface, drawing in Merdo the Wizard, whose magic may hold the key to unraveling the mystery. With danger lurking beneath the waves and the truth hidden behind a mask, the line between friend and foe grows dangerously thin.
